ČSN EN 15955-2 This document specifies the general safety requirements for demountable machines and trailers, including road-rail trailers - henceforward referred to as 'machines', for use when travelling and working on railway track. NOTE 1 - Trailers, including road-rail trailers, are considered as machines because they are moved along the track by powered machines. This document specifies the requirements to deal with the common hazards presented by their use on the railway during transport, assembly and installation, commissioning, travelling and working on track, use including setting, programming, and process changeover, operation, cleaning, fault finding, maintenance and de-commissioning of the machines and associated equipment when they are used as intended and under conditions of misuse which are reasonably foreseeable. These machines will not run on railway lines open to normal traffic. NOTE 2 - Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other European standards, see Technical Report CEN/TR 17498:2020. This document is also applicable to machines and associated equipment that in working mode are partly supported on the ballast or the formation. The requirements in this document are based on the assumption that the machines are used, operated and maintained by skilled person(s). This document does not include requirements for: - quality of the work or performance of the machine; - use of separate equipment temporarily mounted on machines; - machines that utilize external power supplies such as the overhead contact line system for traction purposes or as a power source; - hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h; - operation subject to special rules, e.g. potentially explosive atmospheres; - hazards due to natural causes, e.g. earthquake, lightning, flooding; - working methods; - operation in severe working conditions requiring special measures, e.g. corrosive environments, contaminating environments, strong magnetic fields; - hazards occurring when used to handle suspended loads which may swing freely.

ČSN EN IEC 61400-4 ed. 2 This part of IEC 61400 is applicable to enclosed speed increasing gearboxes for horizontal axis wind turbine drivetrains with a power rating in excess of 500 kW. This document applies to newly designed gearboxes for wind turbines installed onshore or offshore. The technical requirements given in this document are not intended for repaired or refurbished gearboxes, or for the extension of the service life beyond the design life. This document provides requirements and guidance on the analysis of the wind turbine loads in relation to the design of the gear and gearbox elements. The gearing elements covered by this document include such gears as spur, helical or double helical and their combinations in parallel and epicyclic arrangements in the main power path. This document does not apply to power take off (PTO) gears. This document includes requirements, design recommendations, and rating of gearboxes with rolling bearings, plain bearings, or combinations of both bearing types. Also included are requirements and guidance on the engineering of shafts, shaft hub interfaces, lubrication, wind turbine controller interface, and the gear case structure to achieve a design that is capable of withstanding the environment and operating conditions of a wind turbine. Requirements for dynamic analysis of the gearbox within the wind turbine system are specified for the purpose of identifying load levels exceeding the predictions of the global aeroelastic simulation. The analysis of noise transmission and emission (e.g. tonal emission at gear mesh frequencies) is not within the scope of this edition of the document. Further, this document provides requirements and guidance on gearbox design verification, prototype testing and production testing, as well as consideration of design for service and maintenance.
